可以用任何方法？好！用matlab，并且是精确值，四组解：>> [x,y]=solve('x^2+y=11','x+y^2=7') x =3-(1/6*(1268+12*i*6303^(1/2))^(1/3)+68/3/(1268+12*i*6303^(1/2))^(1/3)-2/3)^2+7 -(-1/12*(1268+12*i*6303^(1/2))^(1/3)-34/3/(1268+12*i*6303^(1/2))^(1/3)-2/3+1/2*i*3^(1/2)*(1/6*(1268+12*i*6303^(1/2))^(1/3)-68/3/(1268+12*i*6303^(1/2))^(1/3)))^2...
